A long-serving Liberal Democrat councillor and former mayor of Harrogate has been suspended by her national party over a series of “antisemitic” comments about the Israeli offensive in Gaza.

Shortly after learning of Councillor Pat Marsh’s comments on Twitter in which she described Jews as “vile”, “evil” and “a disgrace to the world”, the national party said it had also launched an investigation into the remarks, while North Yorkshire Council’s Liberal Democrats immediately suspended her from the group.

A spokesperson for the national Liberal Democrat Party said: “These appalling antisemitic views have no place in our party. Ms Marsh has been removed from the council group and has been reported to the council’s standards officer.”

Liberal Democrat group leader on the authority, Councillor Bryn Griffiths, added: “These comments in no way represent our group or our views.”

Speaking after her suspension, Coun Marsh, who has represented Harrogate residents for more than three decades, said the series of comments she made between January 22 and Friday highlighted her opposition, “as a grandmother and a mother to the slaughter of 14,200 innocent children”.

The posts included: “Hope you Jews feel proud of yourselves. Remember what happened to you during the Second World War why would you do the same? Act like adults and get round the table to get a fair and lasting solution.”

Another post stated: “We can’t believe what your Jewish country is doing to Palestinians it is outrageous, killing children cutting off their hands and other atrocities do you not feel frightened for them!!!”

When asked why she had repeatedly referred to Jews rather than Israel in the posts, Coun Marsh said: “It’s them that I am seeing abusing children. I suppose it’s Israel, but they are all Jewish aren’t they? I don’t think you can live in Israel without being a Jew.

“I am against what they are doing to the Gazan people. I’m just trying to be a human being. I’m not antisemitic, it’s the fact it’s they are the ones doing it at the moment.  I can’t say you naughty French or German people. It is being done by Israelis.”

However, numerous councillors said they had been shocked by Coun Marsh’s comments, and condemned them as “abhorrent” before calling for her to resign as a councillor.

Councillor Steve Shaw Wright, the council’s Labour group leader, said: “I’m speechless. It shouldn’t be a suspension matter, it’s a resigning matter.”

Conservative councillor for Helmsley division, George Jabbour, an immigrant from Syria, said he had submitted a complaint to the council as “these repulsive remarks breach several code of conduct obligations” elected members must follow.

Leader of the council’s Independent group, Councillor Stuart Parsons said: “The consequences of the war are horrendous, but this is not a Jewish question. It’s a question for the state of Israel and Jewish community in this country have nothing to do with what Israel decides it must do.”
